Observer agreement on cephalometric landmarks was compared between xeroradiographs and conventional radiographs of twenty-nine patients. Of fourteen landmarks evaluated, four (condylion, infradentale, Ptm, and ANS) demonstrated clinical significance in favor of the xeroradiograph. In addition, six other landmarks favored the xeroradiograph but not to the degree of statistical significance.
比较了29例患者的干板X线片和传统X线片在头颅测量标志点上的观察者一致性。在评估的14个标志点中,有4个(髁突点、下齿槽座点、翼上颌裂点和鼻前棘点)在支持干板X线片方面具有临床意义。此外,其他6个标志点更支持干板X线片,但未达到统计学显著程度。
